With any documents, the office makes a working directory of the form
/home/test/.local/share/onlyoffice/desktopeditors/recover/DE__d0pJOd where the actual work with the new version of the file takes place.
Saving a document copies the new version of the document to its original location. Often there is a situation when two or three users open a file for work and as a result we get a document in the form in which it was retained by the last editor. All changes made by other users are lost.
I ask you to implement the blocking function based on the creation of Owner File ,
which will also enable collaboration with Microsoft Office users.
